Class MBeanJob

java.lang.Object
  org.backsource.qcron.MBeanJob

All Implemented Interfaces:

org.quartz.Job, java.io.Serializable

public class MBeanJob

extends java.lang.Object

implements org.quartz.Job, java.io.Serializable

A Quartz job that will delegate to an MBean.

Delegation is enforced by saving a the MBeanJob in the JobDataMap of the JJobDetail this is connected to. Since MBeanJobb is a serializable class this wil work even if JobDataMap is saved to peristent store. To make this work one have to create an MBeanJob and set it in the JobDataMap of the JobDetail that should have this job as its executor, eg:

      jobDetail = new JobDetail(name,
                                group,
                                MBeanJob.class
                                );
      MBeanJob job = new MBeanJob( jobDetail.getJobDataMap(),
                                   jobObjectName);

This will the work automagically.
